BACKGROUND OF INVENTION

In recent years there has been an increasing use of hydrotherapy jets in pools, spas, tubs, and similar water containing structures. Hydrotherapy jets of various configurations are well known in the art and are readily commercially available. Such hydrotherapy jets typically are mounted behind an opening in a peripheral wall of a pool or spa and discharge a water stream or a stream of water and air through an orifice that typically directs the flow of the stream below the surface of the water. Some hydrotherapy jets include a manually adjustable directional element that enables a user to select the direction of stream. The hydrotherapy jet itself, however, remains stationary. The user must then move his body relative to the stream to massage an area of the body inaccessible by merely manipulating the directional element. In other words, to massage these inaccessible areas of the body, the user has to shift their body position such that the output jet stream is directed towards the desired area.

SUMMARY OF INVENTION

DETAILED DESCRIPTION OF SOME EMBODIMENTS OF THIS INVENTION General

The hydrotherapy apparatus and method of this invention is adapted for use within pools, and it includes a conventional hydrotherapy jet 12. For example, a suitable hydrotherapy jet is illustrated in U.S. Pat. No. 5,848,444. The hydrotherapy jet 12 is attached to a mounting structure that immerses the hydrotherapy jet into the water in the pool. The mounting structure is manually adjustable to move the hydrotherapy jet into different positions to direct a pressurized water jet against different parts of the body of a person in the pool. Water in the pool is circulated through the hydrotherapy jet continually or intermittently. The many modes of attachments illustrate herein depicted the general principle of this invention, one of which mounts the hydrotherapy jet 12 to a floating structure and another of which mounts the hydrotherapy jet 12 directly to a wall of a pool. The various embodiments illustrate different means of attaching the hydrotherapy apparatus of this invention to a floating structure or a wall of a pool. As shown by the following embodiments, there are many adaptations for securing the hydrotherapy apparatus within either above or in-ground pools. The apparatus as described herein permits the user to adjust manually the water jet stream in selected directions and the user does not need to move his/her body relative to the stream to massage an area of the body. To massage other areas of the body, the user can further adjust the hydrotherapy jets such that the output jet stream is directed towards the desired body area. The apparatus as described and illustrated enables a user to treat selected body areas immersed in the water in a pool. The apparatus may be moored to a side of the pool or support the user while he or she floats in a seated or reclining position, or and the user selects the positioning of hydrotherapy jet by moving the entire jet relative to the user's body. More than one hydrotherapy jet may be in the hydrotherapy apparatus of this invention, and a plurality of apparatus can be utilized to treat more than one individual user simultaneously.

FIGS. 1 Through 5

FIGS. 1 through 5 illustrate one embodiment of the hydrotherapy apparatus of the present invention generally designated by the numeral 10. The hydrotherapy apparatus 10 includes the hydrotherapy jet 12, a planar, a U-shaped mounting structure 14, a floating recliner 16, and an adjustable rod assembly 18 attaching the recliner 16 to the U-shaped mounting structure 14. The floating recliner 16 has a seat 11, a floatable headrest 42, and floatable armrests 44 that allow the user to float and sit comfortably, resting his/her head and either or both arms while utilizing the hydrotherapy apparatus 10. The U-shaped mounting structure 14 is positioned under a bumper 46 and fastened thereto on the underside of the bumper by hook and fabric connectors 31 such as sold under the trademark Velcro. Alternatively, the bumper may be sewn, heat bonded, or molded as a unitary, one-piece structure to the headrest 42. A rope or the like 32 attached to a topside of the bumper 46 moors the hydrotherapy apparatus 10 to an umbrella pole 7 at the side of an in-ground swimming pool to maintain the floating recliner 16 in substantially the same location in the pool. The bumper 46 has a passageway 23 (FIG. 3) through which pass a water line 22 and an airline 22 a. These lines 22 and 22 a also pass between the legs 14 a and 14 b of the U-shaped mounting structure 14 and are connected to the hydrotherapy jet 12.

While a user is sitting in the floating recliner 16 as shown in FIG. 1, a high velocity stream or jet of water and air from the hydrotherapy jet 12 impinges against the user's back at a location selected by manually positioning the adjustable rod assembly 18. Air is drawn into a water stream flowing through the hydrotherapy jet 12 to provide the jet of water and air. The water line 22 extends from a pump 20 and is attached to an inlet 12 a (FIG. 5) of the hydrotherapy jet 12. The separate airline 22 a is attached to an inlet 12 b (FIG. 5) of the hydrotherapy jet 12. The pump 20 pumps water from the pool or other water containing structure through the water line 22 in communication with the water hydrotherapy jet 12. Concurrently, air is sucked by a venturi through the airline 22 a into the water stream exiting hydrotherapy jet 12.

As best shown in FIGS. 2 and 3, the hydrotherapy apparatus 10 includes a holder 9 for the hydrotherapy jet 12 having an open front and an open back. A pair of aligned arms 4 project outwardly from dosed, opposite sides of the holder 9. These arms 4 are positioned to grasp or slide along a pair of parallel straps 9 a extending from the headrest 42 to the seat 11 of the recliner 16. These arms 4 and the adjustable rod assembly 18 allow the user to move the hydrotherapy jet holder 9 upward and downward along the straps 9 a. Side arm straps 6 of the recliner 16 may be adjusted by multiple buckles 8 on the straps to vary the length of the straps such that the user can rest his/her arms comfortably while utilizing the hydrotherapy apparatus 10. The hydrotherapy jet 12 is adjusted or manipulated into position through adjustments to rotatable and lockable cams 24, 26, 28 of the rod assembly 18.

FIG. 4 shows in greater detail the way the hydrotherapy jet 12, its holder 9, and the rod assembly 18 are attached to the U-shaped mounting structure 14 and the recliner 16. The rod assembly 18 includes rigid rods 18 a and 18 b connected together by the lockable cams 24, 26 and 28. The relative positions of the rods 18 a and 18 b are adjusted utilizing the lockable cams 24, 26 and 28, which are unloosened by rotating in one direction and tightened by rotating in the opposite direction. One end of the rod 18 a is secured by the lockable cam 28 to the mounting support 14. The position of the rod 18 a is adjusted by unloosening the lockable cam 28 by rotating in one direction, positioning the rod 18 a, and then rotating lockable cam 28 in the opposite direction to hold the rod 18 a in the selected position. The end of the rod 18 b is connected by the lockable cam 24 to the hydrotherapy jet holder 9, and the adjacent ends of the rods 18 a and 18 b are connected together by the lockable cam 26. Loosening the cams 24, 26 and 28 enables the user to manipulate the rods 18 a and 18 b and hydrotherapy jet holder 9 to provide upward and downward adjustment along the user's body to select the location that the high velocity stream or jet of water will strike the user's back while sitting in the floating recliner 16. Tightening these cams 24, 26 and 28 holds the hydrotherapy jet 12 in the selected position. As shown, the rod assembly 18 is adjusted to provide an offset of a suitable distance from an adjacent pool wall W such that the hydrotherapy apparatus 10 has adequate clearance from the wall.

FIGS. 6A Through 6D

FIGS. 6A through 6D show an alternate embodiment of the hydrotherapy apparatus of this invention generally designated by the numeral 10 a. The hydrotherapy apparatus 10 a is designed to be attached to a top edge E1 of the wall W of an above ground pool as shown in FIG. 6C or to a location nearby a sunken or in-ground pool as shown in FIG. 6D.

The hydrotherapy apparatus 10 a includes the hydrotherapy jet 12 as discussed above and a mounting structure MS that has four (4) main components: (1) an L-shaped mounting structure 14A including a plate p1 at a right angle to a plate p2 having central opening 5 for the lines 22 and 22 a and a recessed ledge 25, (2) a stepped bracket 14B having a normally vertically oriented planar section 27 a disposed at a right angle between a normally horizontally oriented planar section 27 b and a pair of normally horizontally oriented planar arm members 27 c and 27 d, (3) a bracket 14C including a cross-plate 13 to which is attached a pair of bent support members 13 a and 13 b each terminating in free ends 13 c 1 and 13 c 2, respectively, and (4) a yoke member 14C including a tubular section 15 disposed between yoke arms 15 a and 15 b. The components 14A, 14B, and 14C are detachably connected together by any suitable fastener such as bolts (not shown). Specifically, the planar section 27 b of the stepped bracket 14B is inserted into the recessed ledge 25 and bolted in position, and the cross-plate 13 of the bracket 14C is bolted to the planar arm members 27 c and 27 d. Each arm member 27 c and 27 d has a longitudinal slot 29 a and 29 b therein aligned with holes H1 and H2 in the plate 13 through which bolts pass for adjustably connecting the bracket 14C to the arm members. Moving the bracket 14C relative to the stepped bracket 14B prior to fastening these brackets together allows the cross-plate 13 to be moved towards or away from the plate P1 of the L-shaped mounting structure 14A to offset the hydrotherapy apparatus 10 and the floating recliner 16 from the pool wall W a suitable distance to provide adequate clearance. The yoke member 14C has its arms 15 a and 15 b connected respectively to the free ends 13 c 1 and 13 c 2 of the bracket 14C by a rotatable locking cam C2, which functions like the cams 24, 26 and 28. This enables the user to adjust the angular relationship between the arms 15 a and 15 b and the support members 13 a and 13 b. To moor the hydrotherapy apparatus 10 a, the umbrella pole 7 passes through the tubular section 15 of the yoke member 14C and has a pointed tip (not shown) buried in a pot 35 resting on the surface of the ground.

In accordance with one feature of the hydrotherapy apparatus 10 a, the bracket 14C may be connected in two alternate arrangements. In one arrangement as shown in FIG. 6C, the plate 13 is attached to undersides S1 of the planar arm members 27 c and 27 d of the stepped bracket 14B. The locking cam C2 has been locked so the planar arm members 27 c and 27 d and the support members 13 a and 13 b of the bracket 14C form an obtuse angle A, and the support members 13 a and 13 b are below the elevated edge E1 of the pool and point downward towards the ground away from the edge E1 of the pool. This arrangement is used when mooring to an above ground pool.

The other arrangement shown in FIG. 6D is used when mooring to an in-ground pool, and the bracket 14C has been inverted from the position shown in FIG. 6C. The plate 13 is now attached to top sides S2 of the planar arm members 27 c and 27 d of the stepped bracket 14B, and the locking cam C2 has been locked so the planar arm members 27 c and 27 d and the support members 13 a and 13 b of the bracket 14C are substantially aligned. In this inverted position, the support members 13 a and 13 b are above the edge E1 of the pool and point downward towards the edge E1 of the in-ground pool.

FIGS. 7 and 8

A further embodiment of the hydrotherapy apparatus of this invention is generally designated by the numeral 10 b. This hydrotherapy apparatus 10 b is fastened directly to the pool wall W as illustrated in FIG. 7 and does not employ a floating recliner. As depicted in FIG. 8, the hydrotherapy apparatus 10 b includes the holder 9 containing the hydrotherapy jet 12 with an end of the adjustable rod assembly 18 connected to a mounting mechanism comprising a pair of detachable, interconnected plates 30 and 30 a. The plate 30 has a keyhole cutout 36 along one edge and a socket 28 a, which is attached directly to this plate 30, for the rotatable lockable cam 28 of the rod assembly 18. The other plate 30 a, which is fastened directly to the pool wall W, contains a knob-like projection 34 over which the plate 30 slides vertically when this detachable plate 30 is being connected or disconnected to the plate 30 a. This embodiment is meant to illustrate only one type of attachment that could be used for directly anchoring the hydrotherapy apparatus of this invention directly to a pool wall without using a floating recliner.

FIGS. 9 Through 14

FIGS. 9 and 10 depict one alternate embodiment of the hydrotherapy apparatus of this invention and FIGS. 11 through 14 each depict other alternate embodiments of the hydrotherapy apparatus of this invention. Each of these alternate embodiments is respectively generally designated by the numerals 10 c, 10 d, 10 e, 10 f, and 10 g. In all these embodiments the rod assembly 18 is replaced with a flexible member such as, for example, a strap, that carries the hydrotherapy jet 12, which slides along the flexible member.

As depicted in FIGS. 9 and 10, the hydrotherapy apparatus 10 c has a floating recliner 16 a with rigid, inflexible side bars 66 connected at their outer ends by a lower front crossbar 54. The straps 6 are fastened to and extend from the ends of the side rods 66 and crossbar 54 to the armrests 44. The straps 6 are adjustable using the buckles 8. The hydrotherapy jet 12 is carried by one piece P1 of a two-piece seating platform 56. The piece P1 functions as a back support and the other piece P2 of the seating platform 56 functions as a seat or bottom support. Both pieces P1 and P2 are moveable, being mounted to slide along parallel flexible straps 57 a and 57 b connected between the headrest 42 and the front crossbar 54. The straps 57 a and 57 b pass through slits S in the pieces P1 and P2 of the seating platform 56. This arrangement enables hydrotherapy jet 12 to be adjusted up and down along the straps 57 a and 57 b as shown in FIG. 9 by the arrows indicating directional motion. Optionally, hand straps 48 are positioned on the armrests 44 to facilitate the user getting into and out of the recliner 16.

The hydrotherapy apparatus 10 d depicted in FIG. 11 employs side bars 66″ (only one shown) that are adjustable through the use of a rotatable lockable cam 52 like those discussed above. This allows for variations in position of the jet stream from hydrotherapy jet 12 interacting with the body of a user sitting in the recliner 16 a.

The hydrotherapy apparatus 10 e depicted in FIG. 12 employs more than one hydrotherapy jet, namely, jets 12A and 12B, both slideable independently up and down along the straps 57 a and 57 b. Side support bars 66″ are telescopically adjustable, each side bar including a main rod 66A secured to a recliner frame (not shown) and a secondary rod 66B movable within the main rod 66A. Conventional adjusting means 108 comprising spring loaded buttons B within the secondary rod 66B interact with a series of holes 1 in the main rod 66A enable the length of the side bars 66″ to be increased or decreased by increments. This incremental increase or decrease allows for variations in the position the hydrotherapy jets 12A, 12B interacting with the body of a user. The upward and downward direction of motion is indicted by the arrows. The multiple hydrotherapy jets 12A and 12B can be moved in the direction of the arrows individually in either direction to provide for multiple jet streams to be focused simultaneously towards more than one desired area of the user's body.

The hydrotherapy apparatus 10 f depicted in FIG. 13 has a floating recliner 16 b wherein a top portion comprises a float 59 (such as the armrests) and a bottom portion 60 comprises a porous, flexible material such as a piece of mesh or cloth attached to a recliner frame (not shown) in a manner similar to that of a hammock.

The hydrotherapy apparatus 10 g depicted in FIG. 14 has a floating recliner 16 c with a firmer seat 62 such as one formed by a rigid material as, for example, a molded or formed plastic material held in place by straps 6 which are adjustable via buckles 8.

FIGS. 15 Through 19

FIGS. 15 and 16 depict one alternate embodiment of the hydrotherapy apparatus of this invention generally designated by the numeral 10 h, FIG. 17 depicts other alternate embodiment of the hydrotherapy apparatus of this invention generally designated by the numeral 10 i, and FIGS. 18 and 19 depict still another alternate embodiment of the hydrotherapy apparatus of this invention generally designated by the numeral 10 j. All these different embodiments employ a floating recliner with a rigid frame F having the conventional adjusting means 108 to enable the long dimension of the frame to be increased or decreased by increments. The common features of the frame F in all these embodiments 10 h, 10 i, and 10 j is an arrangement of tubular members TM forming at least a portion of an outline or boarder for a back BB and seat SS of a floating recliner. Fabric material FM extends between and around portions of the tubular members TM to form at least portions of the back BB and seat SS. The flexible material FM may be impervious to water or partially impervious to water. The seat SS may be fabricated from a plastic sheet or injection molded.

The back BB of the frame F of the hydrotherapy apparatus 10 h includes a U-shaped upper tubular element 74 a having an upper cross member C1 extending between parallel legs L1 and L2. Its seat SS includes a U-shaped lower tubular element 74 b having a lower cross member C2 extending between bent, parallel legs L1′ and L2′. The ends of the legs L1 and L2 are received telescopically in open ends of the legs L1′ and L2′, enabling the overall height of the back BB to be increased or decreased and allowing adjustment of the headrest 42. The arrows indicate the direction of motion along the tubular elements 74 a and 74 b. The fabric material FM is stretched across a lower portion of the legs L1′ and L2′ to provide the seat SS. The back BB includes the straps 57 a and 57 b carrying the piece P1 holding the hydrotherapy jet 12 as discussed above (The piece P2 is eliminated in the hydrotherapy apparatus 10 h). The upper ends of the straps 57 a and 57 b are connected to the upper cross member C1 and the lower ends of the straps 57 a and 57 b are connected to an inner edge of the fabric material FM. Flexible fabric straps 80 of a fixed length extend between the outer ends of the floatable armrests 44. This embodiment maintains a fixed distance for the front portion of the floating recliner while allowing for adjustment of the rear portion of the recliner to suit the individual preferences or requirements.

As illustrated in FIG. 17, the back BB and seat SS of the frame P of the hydrotherapy apparatus 10 i is similar to that of the hydrotherapy apparatus 10 h. The main difference between these two embodiments 10 i and 10 h is the use of a lower frame LF comprising a U-shaped tubular element 94 and a cross member C3. The opposed ends of the cross member C3 are T-shaped tubes T1 and T2 and the legs L1″ and L2″ of the U-shaped tubular element 94 pass respectively through these tubes. The ends of the legs L1 and L2 of the U-shaped tubular element 74 a are inserted telescopically into open ends of the legs L1″ and L2″ of the U-shaped tubular element 94. An adjustable strap 82 including a buckle 8 extends between a central portion of the cross member C3 and a central portion of a cross member C4 of the U-shaped tubular element 94. Connecting the U-shaped tubular elements 74 a and 94 creates a rectangular frame structure that carries the seat SS. The seat SS may be moved along this rectangular frame structure, and the U-shaped tubular elements 74 a and 94 may be moved relative to each other to alter the dimension of the rectangular frame structure. Adjustments in the length of straps 57 a and 57 b and the strap 82 are made accordingly as the dimension of the rectangular frame structure are altered. The straps 57 a and 57 b apply a tensioning force to the seat SS in one direction and the strap 82 applies a tensioning force in the opposite direction, to retain the seat SS in a selected position.

As illustrated in FIGS. 18 and 19, the hydrotherapy apparatus 10 j is substantially the same as the hydrotherapy apparatus 10 i, except an enlarged, planar piece 100 carrying a plurality of hydrotherapy jets 12 is mounted to slide along the straps 57 a and 57 b.

FIGS. 20A Through 20D

FIGS. 20A through 20D depict another alternate embodiment of the hydrotherapy apparatus of this invention generally designated by the numeral 10 k. The hydrotherapy apparatus 10 k includes a recliner 102 having a rigid, rectangular frame 103 that is not adjustable to change its dimensions. A seat 104 carried by the frame 103 includes a rigid curved bottom support 104 a typically molded from a plastic such as, for example, polypropylene, and a rigid curved back support 104 b typically molded from a plastic such as, for example, polypropylene. Typically, the polypropylene has a density slightly greater than water. The bottom support 104 a has a curvilinear cross-sectional configuration with substantially aligned, spaced apart substantially rectangular slots 114 a, 114 b, 114 c, 114 d, and 114 e in its rear portion and a pair of substantially aligned, spaced apart rectangular slots 115 a and 115 b in its front portion. It may include the headrest 42, floatable armrests 44, and bumper (not shown) attached in essentially the same manner as discussed above.

Adjustable straps 157 a and 157 b connect the top of the frame 103 to the bottom support 104 a having portions thereof passing through the back support 104 b. The back support 104 b is bowed to conform at least partly to the back of a user and includes multiple slots S4 in two rows A1 and B1. The strap 157 a passes through the slots S4 in the row A1 and the strap 157 b passes through the slots in the row B1. The back support 104 b includes one centrally located hydrotherapy jet 12, and like some other embodiments the back support has dimensions that enable it to fit and move within the space between the bottom support 104 a and the top and sides of the frame 103.

The frame 103 may be made of PVC welded together tubes, or it may be a substantially solid structure comprising a substantially U-shaped, substantially solid member 103 a and a substantially straight, solid member 105 a connected to the U-shaped member. A solid structure avoids collecting water within the frame 103, in contrast to tubes, which may collect water therein. The U-shaped member 103 a has a pair of substantially parallel legs 105 b and 105 d, each terminating in an open end E2 a and E2 b, respectively. The ends E2 a and E2 b are opposed to each other. The legs 105 b and 105 d have a rectangular cross-sectional configuration of dimensions that allow them to pass through the slots 114 a and 114 e, respectively. The lower ends of the legs 105 b and 105 d are integral with a connector piece 105 c having a central recess 113 receiving a lower portion the strap 82. The straight connecting member 105 a extends between the open ends E2 a and E2 b and has a substantially cross-shaped cross-sectional configuration as shown in FIG. 20C to enhance the rigidity of the frame 103.

One end of the connecting member 105 a is enlarged to provide a stop element S3 engaging an exterior surface of the leg 105 d with an intermediate portion of the connecting member 105 a disposed between the open ends E2 a and E2 b of the legs 105 b and 105 d. As illustrated in FIG. 20D, the other end of the connecting member 105 a has an enlarged cylindrical configuration that abuts the interior surface of the leg 105 b and includes a cavity 110 into which a retainer 112 is force fitted upon assembly of the U-shaped member 103 a and straight member 103 b. The retainer 112 has a pair of flexible and resilient prongs 112 a that are depressed as the retainer is pushed into the cavity 110. When the retainer 112 is properly positioned in the cavity 110, the prongs 112 a spring outward to engage opposed holes 110 a (only one shown) in a wall of the cavity 110 to hold the retainer 112 in position by means of catch elements 111 on the prongs.

Typically, the components of the hydrotherapy apparatus 10 k are delivered to a user unassembled, who manually attaches them together. The legs 157 a and 167 b are pushed respectively through slots 114 a and 114 e in the rear of the bottom support 104 a and then the connecting member 105 a is connected as discussed above using the retainer 112 to secure the frame components together. The straps 80 and 82 and straps 157 a and 157 b are then connected as illustrated and adjusted to raise or lower the bottom support 104 a, which is guided by the legs 157 a and 167 b as it moves, and to position the back support 104 b at a selected location relative to the back of the user sitting in the recliner 102.

In this embodiment as illustrated in FIG. 20C, the straps 157 a and 157 b are wound around the connecting member 105 a with one free end of each strap respectively passing through the slots S3 in each row A1 and B1 and through the slots 114 c and 114 d and then being connected to another free end by the buckles 8. The straps 80 each extending downward from an outer end of the floatable armrests 44 each have a looped portion carrying a stop member 116 that slides along the looped portion when the straps 80 and the straps 157 a and 167 b are adjusted to raise or lower the bottom support 104 a. The stop member 116 engages an underside of the bottom support 104 a after adjustment. The strap 82 is centrally attached, having a portion passing through the slot 114 c and another portion wrapped around the connector piece 105 c, with the buckle 8, permitting the length of the strap 82 to be adjusted to provide tension after the bottom support 104 a and back support 104 b are positioned as desired. Thus, the bottom support 104 a and back support 104 b are moveable relative to each other so the hydrotherapy jet 12 is adjustable to direct the water jet against different parts of the body of a person sitting in the rediner 12.

FIGS. 21A Through 21C

FIGS. 21A through 21C depict still another embodiment of the hydrotherapy apparatus of this invention generally designated by the numeral 10 l. The hydrotherapy apparatus 10 l is similar to the hydrotherapy apparatus 10 k, but employs only two straps 200 a and 200 b. The hydrotherapy apparatus 10 l includes a pair of buckle base components BC1 as portions of the rigid back support 104 b that are integral therewith and formed during molding of the back support, and a pair of buckle base components BC2 as portions of the rigid bottom support 104 a that are integral therewith and formed during molding of the bottom support. Each of the buckle base components BC1 and BC2 has a lever element 202 hingedly connected thereto to form a buckle. When the lever element 202 is opened by pivoting it outward away from the buckle base component as shown in FIGS. 21B and 21C, a portion of a strap passing between the lever element is free to move up and down. When the lever element 202 is dosed by depressing it, pushing it towards the buckle base component, a portion of a strap between the lever element and the buckle base component is gripped firmly therebetween, preventing the strap from moving up and down.

As depicted in FIG. 21A, each buckle base component BC1 is aligned with the buckle base component BC2 directly beneath it, so the strap 200 a engages the buckle base components BC1 and BC2 on the left side of the hydrotherapy apparatus 10 l and the strap 200 b engages the buckle base components BC1 and BC2 on the right side of the hydrotherapy apparatus 10 l. The opposed ends of the straps 200 a and 200 b are connected respectively to the top and bottom of the solid frame 103, being spaced apart and extending substantially parallel to each other. The top end of each strap 200 a and 200 b is looped around the straight, solid member 105 a of the frame 103 and sewn in position. A free end FE of each strap 200 a and 200 b is first passed through an upper slot S4 in the back support 104 b, then between the lever element 202 and the buckle base components BC1 in the buckle in the back support, then through the lower slot S4. The free ends FE of each strap are then passed through one of the rectangular slot 114 d or 114 b, as the case may be, and then between the lever element 202 and the buckle base components BC2 in the buckle in the bottom support 104 a. These free ends FE are each lopped around the lower connector piece 105 c of the frame 103 and fastened with a buckle 8 to the body of the straps 200 a and 200 b, as the case may be.

When the straps 200 a and 200 b are connected and fastened with the buckles 8 as shown in FIG. 21A, the back support 104 b and bottom support 104 a may be repositioned by simply opening the levers 202 so the back support and bottom support may be manually moved up or down along the straps. When the repositioning has been achieved, the levers 202 are dosed to lock the back support 104 b and bottom support 104 a in the new position.

In both the embodiments 10 k and 10 l of hydrotherapy apparatus of this invention the slots 114 a and 114 e are longer then the long dimension of the legs 105 b and 105 d. This allows the bottom support 104 a to tilt with respect to the horizontal substantially 25 degrees in both the up and down direction for a total of 50 degrees of movement as indicated by the double headed arrow in FIG. 21A.

FIGS. 22 and 23

FIG. 22 illustrates the use of two 74 a and 74 b apparatus 10 in a pool P with one arrangement for the supporting equipment of pump 20, namely, an optional filter 20A and optional heater 20B. The hydrotherapy apparatus 10 are drawn side by side for the purpose of illustration only and other arrangements are possible.

FIG. 23 illustrates an arrangement of two or more hydrotherapy apparatus 10 wherein at least one auxiliary pump 68 is incorporated into the support equipment to provide a consistent water jet stream with a valve V allowing control of the water stream.

Water from a return fitting (not shown) in the pool may be used to feed water into the hydrotherapy jet 12.
